BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forced-ventilation type refrigerator having a freezing compartment and a refrigerating compartment, and a low temperature compartment having an independent door.

2. Description of the Related Art In recent years, in order to preserve fresh food such as fish meat, a refrigerator for home use has an independent door in addition to a conventional refrigerating room,
It is becoming mainstream to provide a low temperature chamber that enables independent temperature control with a dedicated damper thermostat. Less than,
One example thereof will be described with reference to FIGS. 3 and 4. In the figure, 1 is a refrigerator main body, which is an outer box 2, an inner box 3 and both boxes 2,
It is composed of a heat insulating material 4 filled between the three. Reference numeral 5 is the first partition wall, which internally has a cooler 6 and a blower 7 for forced ventilation.
A cooling chamber 8 containing the above is formed, and a freezing chamber 9 is partitioned and formed in the upper part. Reference numeral 10 denotes a second partition wall, which is located below the first partition wall and defines a refrigerating chamber 11 in the lower part. Reference numeral 12 is a low temperature chamber defined between the first partition wall 5 and the second partition wall 10 and has an independent dedicated door 13. Reference numeral 14 is a duct for guiding the cool air cooled by the cooler 6 to the freezer compartment 9, the refrigerating compartment 11, and the low temperature compartment 12 by the blower 7. Reference numerals 15 and 16 are damper thermostats for adjusting the amount of cold air provided at the entrances of the refrigerating chamber 11 and the low temperature chamber 12 of the duct 14, respectively. Further, 17 and 18 are control panels containing the damper thermos 15 and 16. Reference numerals 19 and 20 denote cold air discharge air passages formed in the control panel 16, communicating with the damper thermostat 15, and opening to the refrigerating compartment 11.

Reference numeral 22 denotes a cool air discharge port that is open to the low temperature chamber 12 in front of the cool air discharge air passage 21. 23 is the refrigerating room
Reference numeral 11 denotes a cool air return air passage, which communicates with the inside of the cooling chamber 8 through both side walls of the low temperature chamber 12. Further, 24 is the low temperature room
12 cold air suction ports for returning cool air communicate with the inside of the cooling chamber 8 directly.

In such a configuration, the cool air cooled by the cooler 6 is controlled by the blower 7 through the duct 14 to the freezing chamber 9, and also after being controlled to an appropriate amount by the damper thermostat 15, and then to the refrigerating chamber 11 through the cool air discharge air passages 19 and 20. Further, after being controlled to an appropriate amount by the damper thermostat 16, it is discharged through the cold air discharge air passage 21 from the cold air discharge port 22 mainly in the front inside the low temperature chamber 12. And the refrigerator compartment 11
Is maintained in a refrigerating temperature zone, and the low temperature chamber 12 is maintained in a temperature zone suitable for keeping fresh food (for example, -3 to 0 ° C). here,
The reason why the cold air discharge port 22 of the low greenhouse 12 is mainly concentrated in the front is that the temperature distribution in the front of the room becomes high due to the influence of the outside air heat entering from the door 13, etc. Therefore, in order to correct this, the front of the high temperature is intensively cooled.

Problems to be Solved by the Invention However, in such a configuration of the low temperature chamber 12, the preserving temperature thereof is set to, for example, a partial freezing (about -3
It is possible to adjust the temperature to chilled (about 0 ° C),
It can always provide only the preserving function limited to one of the temperature zones, and for example, when it is set to partial freezing, chilled food can not be stored due to the risk of freezing,
On the other hand, in the case of chilled setting, there is a disadvantage that the degree of freshness is lowered as compared with the case where fish and meat are frozen and stored by partial freezing, and the degree of freedom for storing food is insufficient.

The present invention is to solve the above-mentioned conventional problems, to expand the freedom of selection of food stored in the low temperature chamber,
The purpose is to improve usability.

Means for Solving the Problems In order to solve the above-mentioned questions, the present invention divides the low temperature chamber into upper and lower parts by a partition plate, and at the lower part thereof, an inner door is provided on the front surface to partition the low temperature room into the upper part. 1 low temperature chamber, 2nd low temperature chamber in the lower stage, each of these 2 chambers is equipped with its own damper thermostat, and for the 1st low temperature chamber, the cool air discharge air duct leading the inside of the top plate forward Is provided for the second low temperature chamber, and a cool air discharge air passage is integrally formed with the partition plate and guided to the front.

Effect The present invention has the above-described configuration, and the temperature of the upper and lower two chambers defining the low temperature chamber can be controlled individually by the respective damper thermostats. By dividing the set temperature zone, it is possible to manage the fresh food according to the desired temperature. At the same time, since the cool air is supplied from the front of the upper surface of the room in both the upper and lower chambers, the high temperature unevenness in the front part of the room is eliminated.
